Johnson Controls GG9S*MP, TG9S*MP Duct Flanges, Floor Base and Ductwork Installation Downflow

Page 5

On all installations without a coil, a removable access panel is recom- mended in the outlet duct such that smoke or reflected light would be observable inside the casing to indicate the presence of leaks in the heat exchanger. This access cover shall be attached in such a manner as to prevent leaks.

The duct system must be properly sized to obtain the correct airflow for the furnace size that is being installed.

Refer to Table 6, "Ratings & Physical / Electrical Data" or the fur- nace rating plate for the correct rise range and static pressures.

If the ducts are undersized, the result will be high duct static pres- sures and/or high temperature rises which can result in a heat exchanger OVERHEATING CONDITION. This condition can result in premature heat exchanger failure, which can result in personal injury, property damage, or death.

DUCT FLANGES

Four flanges are provided to attach ductwork to the furnace. These flanges are rotated down for shipment. In order to use the flanges, remove the screw holding an individual flange, rotate the flange so it is in the upward position and reinstall the screw then repeat this for all 4 flanges.

If the flanges are not used, they must remain in the rotated down posi- tion as shipped.

DUCTWORK INSTALLATION AND SUPPLY PLENUM CONNECTION - UPFLOW/HORIZONTAL

Attach the supply plenum to the furnace outlet. The use of an approved flexible duct connector is recommended on all installations. This connection should be sealed to prevent air leakage. The sheet metal should be crosshatched to eliminate any popping of the sheet metal when the indoor fan is energized.

FLOOR BASE AND DUCTWORK INSTALLATION - DOWNFLOW

Installations on combustible material or directly on any floors must use a combustible floor base shown in Figure 8, "Combustible Floor Base Accessory". Follow the instruc- tions supplied with the combustible floor base accessory. This combustible floor base can be replaced with a match- ing cooling coil, properly sealed to prevent leaks. Follow the instructions supplied with the cooling coil cabinet for install- ing the cabinet to the duct connector. Plug intake and vent pipe holes in bottom panel and move grommet to desired vent side exit.

Downflow Air Conditioning Coil Cabinet

The furnace should be installed with coil cabinet part number specifi- cally intended for downflow application. If a matching cooling coil is used, it may be placed directly on the furnace outlet and sealed to pre- vent leakage. For details of the coil cabinet dimensions and installation requirements, refer to the installation instructions supplied with the coil cabinet.

Attach the air conditioning coil cabinet to the duct connector, and then position the furnace on top of the coil cabinet. The connection to the fur- nace, air conditioning coil cabinet, duct connector, and supply air duct must be sealed to prevent air leakage.

COIL INSTALLATION

On all installations without a coil, a removable access panel is rec- ommended in the outlet duct such that smoke or reflected light would be observable inside the casing to indicate the presence of leaks in the heat exchanger. This access cover shall be attached in such a manner as to prevent leaks.

TG9S*MP, GG9S*MP specifications

Johnson Controls has long been at the forefront of building efficiency solutions, and their TG9S*MP and GG9S*MP series exemplify this commitment. These two-stage, multi-position gas furnaces are designed for optimal comfort and performance in residential applications, and they come packed with a variety of features that enhance their efficiency and operational capabilities.

One of the standout features of the TG9S*MP and GG9S*MP furnaces is their efficient two-stage operation. This technology allows the unit to operate at a lower capacity most of the time, which translates into reduced energy consumption and costs. When the demand for heating increases, the furnace automatically shifts to a higher capacity, ensuring a consistent and comfortable indoor temperature. This flexibility not only enhances comfort but also extends the lifespan of the unit as it doesn't have to work harder than necessary.

Energy efficiency is a crucial characteristic of both models. With an Annual Fuel Utilization Efficiency (AFUE) rating of up to 96%, these furnaces convert a significant amount of the fuel they consume into usable heat. Such efficiency ratings not only help in reducing energy bills but also have a positive impact on the environment by minimizing greenhouse gas emissions.

Both models feature advanced technology in their design, including a fully modulating gas valve and a variable-speed blower motor. The modulating valve adjusts the gas flow in response to the thermostat’s signals, allowing for precise temperature control and improved comfort. Meanwhile, the variable-speed blower motor enhances airflow while operating quietly, significantly improving overall indoor air quality by promoting even heat distribution throughout the home.

From a structural standpoint, the TG9S*MP and GG9S*MP are built with durable materials designed for longevity. Their compact design allows for flexible installation options, whether in a closet, attic, or basement. The furnaces also come equipped with a robust heat exchanger crafted from high-quality materials, which ensures both reliability and efficiency.

In conclusion, the Johnson Controls TG9S*MP and GG9S*MP furnaces provide homeowners with efficient, reliable, and comfortable heating solutions. With advanced features such as two-stage operation, impressive AFUE ratings, and modern technology integrations, these models stand out in the market as dependable options for both energy savings and year-round comfort. Whether you're a homeowner looking to upgrade your heating system or a contractor seeking high-quality products for your clients, these furnaces represent a smart choice.
